Very repetitious. Seven cells of nine. Very repetitious. Same pattern many times.
When I don’t tell you what song I’m thinking of, and also change the lyrics, I assume it doesn’t make much sense at all.
Rules:
Normal Irregular Sudoku rules apply. (There are nine regions of nine cells each, but they are not 3x3 squares.)
Digits within cages do not repeat, and sum to the total in the top-left corner of the cage.
Cells separated by a chess Knight’s move do not contain the same digit.
Estimated difficulty: 2 out of 5
